When it needs to be sealed, Gaynor Industries has the brands you can trust: BarTite, BarClad, and BarPad.

Since 1954, Gaynor Industries has provided American-made sealing washers to industries as varied as outdoor lighting, marine, electronics, filtration, and automotive. It is because of our solid reputation for innovation, quality, and environmental responsibility that Gaynor Industries remains the preferred supplier to many OEM's and distributors for delivering quality sealing fasteners.

Nearly 60 years ago, BarTite Sealing Washers were introduced as one of the first "one-piece washer" designs developed and patented in the United States. Today, Gaynor Industries operates out of a 15,000 square-foot-facility in Wilmington, MA and has invested heavily in streamlining processes and expanding production capabilities. We are committed to delivering top-quality products, which include stock and custom sealing washers, nuts and screws.
